The Effects of Different Hitting Test Standards on Test Results

This paper analyses the effects of hitting theory and compression characteristics of the soil on the field rollingpress test, indoor compression test and hitting test, and compares the test results of nine groups of filled material by adopting two heavy hitting test criterions of bigcanister and smallcanister with the same hitting work. It is found that there is a nonlinear relationship between the hitting times and the soil distortion with the same single hitting work. That increasing the hitting times or changing the height of dropping hammer to make the hitting work of per unit volume of the sample tend be the same is not identical to the actual testing results.
